    What are the types of Valves

    Written By: Kashif Zaman Usafzaie‎‏ Valves Uses: Valves are used for: 1. Full flow of full throttle: Which is the wide range of valves use, because valves are designed in a way that reduce pressure losses for fluids passing through these valves, diaphragm valve is used with dangerous and toxic liquids. 2. Flow regulating: Sometimes, we need to regulate flow by changing the valve position between fully open and fully closed and throttling the valve reducing the flow, this is accomplished by using control valves. 3. One-way flow: Sometimes, we need to prevent liquids in the reverse way, this type of valves is installed at pump or compressor discharge lines to…

    what does choke valve mean

    Most Common Choke Valves: •Positive: –Fixed orifice. –Disassemble to change bean. •Adjustable: –Provides variable orifice size through external adjustment. A choke is a restriction in a flow line that causes a pressure drop or reduces the rate of flow. It commonly uses a partially blocked orifice or flow path. Variable Chokes – good for bringing wells on gradually and optimizing natural gas lift flow in some cases. Prone to washouts from high velocity, particles, droplets. Solutions – hardened chokes (carbide components), chokes in series, dual chokes on the well head. Beans are fixed (non adjustable) orifices – ID size is in 64ths of an inch. Choke Uses •Control Flow –…

    The Importance of Cetane Number in Diesel Fuel

    What is Cetane Number? Cetane Number is a measure of the ignition quality of a diesel fuel. It is often mistaken as a measure of fuel quality. Cetane number is actually a measure of a fuel’s ignition delay. This is the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels. Cetane number should not be considered alone when evaluating diesel fuel quality. API gravity, BTU content, distillation range, sulfur content, stability and flash point are also very important. In colder weather, cloud point and low temperature…

    Maximizing Your Job Interview Skills

      in this article we will discuss the things needed to pass the job interview. What is a Behavior Based Interview? ♦ A structured interviewing style based on questions designed to probe past behavior in specific situations. ♦ Focuses on experience, behaviors, knowledge, skills and abilities related to the position. ♦ Used to get an idea of how an individual will manage duties based on their past behavior Note: Past behavior is the best predictor of future performance. Behavioral Interview Behavioral questions are more probing and more specific than traditional interview questions. Behavioral: “Tell me about your greatest achievement? Behavioral: “What did you do when…?” Traditional Interview Traditional interview questions are more hypothetical rather than focusing on past events. Traditional: “Tell me about yourself?” Traditional: “What would you do…

    Hydrate inhibitor injection system

    Hydrate Inhibitors The use of inhibitors is a common practice adopted in gas fields. The reasons are that the well fluids are almost always water saturated and at a rather high pressure. Therefore the cooling due to the fluid throttling at the wellhead choke valves and along the pipeline up to the oil or gas center make it necessary to check if any risk of hydrate formation is to be considered. And, very often, measures to avoid hydrates are to be taken. Generally,   inhibitors are used and the most commonly used inhibitors are: ethylene glycol (EG), diethylene (DEG) and methanol (MeOH). These compounds are injected at the wellhead. At the end of the pipeline,…

    how to become a successful oilfield operator

    Oilfield Operator: first of all, we have to define the routine jobs of the oilfield operator: – observe and check all the process parameters from the control room. – walk in patrols around the process, watch the equipment, report any possible leak, unusual sound or vibration. – write all the field readings such as pressure, temperature or levels and compare them with the values from the control room. and that happens by radio communication with the control room man to make the required adjustments to the valves, level and pressure transmitters. –  start and stop pumps, air compressors, heaters and any other equipment manually. – collect samples from different lines…
